Charge backs with skrill are possible, its harder than paypal but its possible. Verify your account before starting the heavy trades.
To receive funds, people just send to your email and you have to accept them via skrill website.
Yeah, just read this on their help page:
So I guess a scammer just send skrill funds and then go claims that his account was compromised andthe funds were sent by a hacker or something and receives it back?
Guess I just have to keep on looking until I find a safe payment processor with no charge-back policy.
